Definitions

• the invention relates to a mounting screw for fastening of fittings, in particular of strip parts of hollow chamber profiles.
• attachment plates for fastening strip parts to hollow-chamber profiles, which are inserted into a chamber of the hollow profile from the open front side, so that they engage behind the rear side of the wall against which the strip is to rest.
• the mounting plates have threaded holes into which the band part passing through fastening screws are screwed.
• the position of the threaded holes must be introduced into the profile wall in accordance with through holes.
• the position of the through holes is determined for example by means of a drilling template.
• In the band parts and the through holes engaging centering sleeves are used for the exact positioning of the tape, before it is fixed by tightening the mounting screws.
• a device for fastening of fittings to multi-chamber profiles has a mounting screw and a fastening screw, wherein the mounting screw comprises an external thread of a length that several walls of the hollow chamber profile are penetrated with screwed mounting screw.
• the mounting screw comprises an external thread of a length that several walls of the hollow chamber profile are penetrated with screwed mounting screw.
• an opening into the rear end side internal thread is provided, into which the fastening screw can be screwed.
• the mounting screw on its rear end on a collateral collar.
• the fastening screw is screwed into the hollow chamber profile far enough that the abutment collar rests against the outer profile wall.
• the fitting part which must have a matched to the outer circumference of the Vogelbundes center hole, placed and fixed by screwing the mounting screw into the internal thread.
• the invention is therefore an object of the invention to provide a mounting screw, in which the creation of cold bridges is avoided.
• This mounting screw comprises a seen in screwing front part, which comprises a thread and is preferably made of a metallic material see, and a rear part of a heat-insulating material, preferably plastic.
• the external thread of the front part is preferably formed as a self-tapping thread, which during insertion of the mounting screw in holes then forms threads in the hollow profile, in which the external thread of the rear insulating part of the mounting screw while driving it automatically rotates.
• the formation of undesirable cold bridges is reliably prevented because a significant heat transfer to a profile wall, in which the mounting screw engages with its front portion, on the outer wall of the profile, which comes into contact only with the heat-insulating part of the mounting screw does not take place ,
• the front part may have an extension which projects into the rear part.
• This expression is therefore preferred, since the material of the front part has a greater strength than the material of the rear part and thus the formation of the extension on the front part is to be preferred.
• the materials used permit this - to provide the projection on the rear part.
• the extension preferably comprises at least one key surface for effecting the positive connection.
• key surface is meant here an area on the mantle of the extension which has a shape deviating from a cylinder surface.
• the assembly screw according to the invention is particularly easy to produce when the rear part is produced by injection molding and the extension is molded with in the production. A particularly effective form-fit without the need to first produce this by separate means after joining the front and rear parts is thereby ensured.
• the external thread of the mounting screw is formed as a machine thread.
• the external thread of the front part is formed as a self-tapping thread.
• the separate work step of incorporating a female thread into the perforation of the profile becomes superfluous.
• the front portion of the front part may be formed tapered. This makes it easier to find the holes in the profile walls, on the other hand, the threads are incorporated into the holes uniform.
• the assembly screw according to the invention is particularly preferred, in which the rear part comprises a device accessible from its rear end for attaching a turning tool.
• This device may for example have the shape of a hexagon socket.
• This embodiment is particularly suitable for applications in which not very high torques for screwing the mounting screw and cutting the thread are necessary.
• the means for applying a turning tool to the rear end of the extension and the rear part with to provide a through hole for insertion of the rotary tool.
• the torque required for the rotary actuation is introduced via the extension directly into the front part and there is no risk that suffers from the transmission of torque from the rear to the front part of the positive connection between the two parts.
• an embodiment of the mounting screw according to the invention is particularly preferred in which on the lateral surface of the extension two mutually parallel key surfaces are provided by the a through hole extends. If the extension is now encapsulated by the heat-insulating material during the production of the mounting screw, the heat-insulating material penetrates the through-hole and conforms to the wrench surfaces, whereby after hardening of this material a firm, form-fitting connection in both the axial and in the axial direction Direction of rotation exists.
• the mounting screw may have at its rear, front end a radially projecting head, by means of which the clamping forces are transmitted to the fitting part to be fastened.
• a variant is preferred in which from the rear end-side end in the rear part of the mounting screw an internal thread is incorporated, in which then - as known from the prior art - a fitting passing through the fastening screw is screwed.
• FIG. 1 shows a first embodiment in a separate representation of the front and rear parts in a perspective side view.
• Figure 2 shows the same embodiment in the same view, but in longitudinal section.
• Fig. 3 shows the embodiment of Figures 1 and 2 again in longitudinal section, but in the assembled state of the front and rear part.
• Fig. 4 shows a second embodiment of a mounting screw according to the invention in a Fig. 2 corresponding view
• FIG. 5 the same embodiment as in Fig. 4 in a Fig. 3 corresponding
• the mounting screw 100 shown in FIGS. 1 to 3 comprises a front part 1 seen in the screwing in direction and a rear part 2.
• the front part 1 has a self-tapping thread 3, which finds its continuation in an external thread 4 of the rear part 2.
• the front part 1 is made of a metallic Material produced.
• an extension 5 connects to the rear, which comprises a cylindrical outer surface 6, in which two mutually parallel key surfaces 7, 8 are incorporated.
• a device for applying a rotary tool 11 is incorporated in the form of a hexagon socket.
• the rear part 2 of the mounting screw 100 is made of a heat-insulating material by injection molding.
• FIGS. 1 and 2 can be misunderstood to the effect that the two parts 1 and 2 could be considered as subsequently connectable. However, this is not the case in the illustrated embodiment.
• the extension 5 is encapsulated by the heat-insulating material in such a way that the heat-insulating material extends through the through-hole 9 and abuts against the wrench surfaces 7, 8, as is apparent from FIG.
• the rear part 2 has a longitudinal bore 12, through which a rotary tool, not shown in the drawing into the device 11 is inserted.
• an internal thread 14 is incorporated, in which a fastening screw, not shown in the drawing as known from the prior art for fastening a fitting part can be screwed.
• FIGS. 4 and 5 A second embodiment of a mounting screw 200 according to the invention is shown in FIGS. 4 and 5. In order to avoid repetition, only the differences from mounting screw 100 will be described below.
• the device 11 for engaging a rotary tool is not provided on the rear end side of the extension 5 in the mounting screw 200, but it is arranged at the end of the longitudinal bore 12 of the rear part 2.
• the mounting screw 100 In contrast to the mounting screw 100 must therefore at the mounting screw 200 torques, which are necessary for incorporation of the thread in profile walls, are transmitted from the rear part 2 to the front part 1.
